H, O, N. T S P and H are the first letters in order for a three sided, four sided and five sided polygon. Triangle. Square. Pentagon and Hexagon. The next polygon is seven sided, a Hexagon. A polygon with eight sides is an Octagon. Lastly, for this puzzle, a nine sided polygon is Nonagon. :)
The series alternates between letters from the beginning and the end of the alphabet: A (1st), Z (26th), E (5th), B (2nd), I (9th), Y (25th), O (15th). Following this pattern, the next letter should be the 3rd letter of the alphabet, which is C. Therefore, the next letter in the series is C.
The answer is C.
d
The answer is C.
c
The series alternates between letters from the beginning of the alphabet and letters from the end, specifically pairing 'a' with 'z', 'b' with 'y', 'c' with 'x', and 'd' with 'w'. Following this pattern, after 'd', the next letter should be 'w'. Hence, the next letter in the series is 'w'.
The next letter in the series BCDEG is "I." The sequence skips the letter "F," resulting in a pattern where every letter after "B" is included except for "F." Following this pattern, after "G," the next letter is "I."
C
A single number, such as 12848384 does not make a series.
The next letter should be N, following the sequence E I L N.
E
I'm convinced that 3,840 is.
